Problems solved by technology

[0007] In addition, prior art terminal receiving cavities or mounting channels formed in the housing create other problems, such as when soldering the connector to the circuit board, through the gap between the terminal and its cavity or channel, possible Tin-attracting action of solder or flux, which may cause contamination of contact parts mated with terminals of mating connectors

Embodiment Construction

[0030] refer to figure 1 , which shows an electrical connector assembly including a connector 10 and a mating electrical connector 50, both of which can be mated together. The connector 10 includes a plurality of terminals 20 arranged in a side-by-side sequence at a predetermined pitch, and a dielectric housing 40 is molded on the terminals 20, preferably by overmolding. The mating connector 50 includes a plurality of contact pins 60 arranged side by side in a one-to-one relationship corresponding to the terminals 20 on the connector of the present invention, and a dielectric housing 80 is overmolded on the contact pins 60 . Such as figure 1 As shown, the terminals 20 and the contact pins 60 are arranged at predetermined intervals in the right-to-left direction, and in addition, perpendicular to figure 1 Arrange them in the direction of the paper plane.

[0031] Each terminal 20 of the connector 20 is preferably produced by pressing and forming it from sheet metal in the s...

Abstract

An electrical connector (10) for mounting to a printed circuit board includes a dielectric housing (40) and a plurality of terminals (20) arranged side by side at predetermined intervals. Each terminal (20) comprises a flat base portion (21) consisting of a continuous folded back portion (23) folded back to one side of the flat base portion (21) and bent to the opposite side of the flat base portion (21) The contact part pair (24) is formed by the bracket coupling section (30) whose sides are substantially at right angles. The housing (40) holds the terminals (20) by overmolding the housing around the flat base portion (21) of the terminals (20) to form a generally flat disk-shaped housing. The contact member pair (24) of the terminal (20) extends toward one surface (40A) of the dielectric housing (40), and the bracket coupling section (30) extends toward the other surface (40B) of the housing (40).

Description

Background technique [0001] The present invention relates generally to an electrical connector suitable for mounting to a printed circuit board, and in particular to a connector for use in solder ball grid array (BGA) applications. [0002] In the past, an electrical connector of this type is known that includes a dielectric housing and a plurality of terminals. 6 and 7 show examples of such prior art connectors, and specifically, FIG. 6 shows one terminal 100 of the connector. A plurality of such terminals 100 are mounted or press-fitted to the housing 200 ( FIG. 7 ) to complete the electrical connector 300 . Although only one terminal 100 is shown in the drawing, actually a plurality of such terminals 100 are arranged side by side at a predetermined pitch. 6, the terminal 100 includes a pair of contact members, or arms 101, a press fit portion 102 formed at the base of the contact members, and a fixed portion formed adjacent to the press fit portion for connection to a sol...
